### Fascinating Cogs

This is the wheel of the Little Vesta.  The mechanism is exposed, so you can have the delight of watching all the cogs doing their work.  The small cog at the top is for the main cam, and the smaller cog on the left is for the bobbin winder.

Cleaning this machine was a long and tedious job.  It took hours with an interdental toothbrush to get all the oily rubbish out from between all the cog teeth.

Because the handle is attached directly to the balance wheel, you get only one turn of the wheel to one turn of the handle, whereas machines with the usual handcrank mechanism give three turns of the balance wheel for each turn of the handle.  This is definitely not the machine to use for curtains with a 90 inch drop.
